Answer:
1/16
Step-by-step explanation:
Here,
Vertex =(3,5)
x= -1, y=6
Simply,eqn of parabola is given by ax^2+bx+c=y
So, coefficient of squared term (x^2) is 'a'
Therefore, we've to find the value of a
Moving on to solution:
a-b+c=6 ___(i) (by putting the given values of x and y in eqn of parabola )
We know that,
Vetex=(-b/2a, ( 4ac-b^2)/4a)
(3,5) = (-b/2a , (4ac-b^2)/4a)
Equating corresponding sides,we get
3= -b/2a
b=-6a___(ii)
Again,
5=(4ac-b^2)/4a
5=(4ac/4a) - (b^2/4a)
5= c- (36a^2/4a) (by putting value of b from eqn ii )
5= c-9a___(iii)
Now,moving back to the first eqn
a+6a+5+9a=6
16a=1
therefore,a=1/16
Hence ,the required value of coefficient of squared term is 1/16.

pls I don't understand the question can u explain
Do you have a calculator? you can solve it by substituting x.
y=16x^2
0: y = 16(0)^2 = 16(0) = 0
(x = 0 , y = 0)
0.5: y = 16(0.5)^2 = 16(0.25) = 4
(x = 0.5 , y = 4)
1: y = 16(1)^2 = 16(1) = 16
(x = 1 , y = 16)
1.5: y = 16(1.5)^2 = 16(2.25) = 36
(x = 1.5 , y = 36)
2: y = 16(2)^2 = 16(4) = 64
(x = 2 , y = 64)
2.5: y = 16(2.5)^2 = 16(6.25) = 100
(x = 2.5 , y = 100)
3 : y = 16(3)^2 = 16(9) = 144
(x = 3 , y = 144)
4: y = 16(4)^2 = 16(16) = 256
(x = 4 , y = 256)
if you multiply a negative number by itself, it will become positive. So, -4, -3, -2.5, -2, -1.5, -1, -0.5 will be the same as the positive 4, 3, 2.5, 2, 1.5, 1, 0.5.
I'm not sure about the pattern, but if you graph it, it'll be symmetrical across the y-axis.
